SpectraCal Releases 4K Test Pattern Generator

SpectraCal, Inc. has released a hand-held portable pattern generator for testing and calibrating new 4K displays.

Called the VideoForge 4K, the affordable new device draws on SpectraCal’s long experience with the original VideoForge software-extensible digital pattern generator. The VideoForge 4K outputs all current 4K formats via Quad-Link SDI, and also supports lower-resolution patterns via Dual-Link SDI, Single-Link SDI, and HDMI.

“Video technology is changing rapidly,” said Jerry Palleschi, president of AVProAlliance. “The VideoForge family is the only solution that can change quickly enough to keep up.”

The VideoForge 4K and VideoForge SDI can generate any one of the billion possible colors inside a display’s color space, making these devices suited for precise display characterization generating a 3D Cube LookUpTable (LUT).
